SPRAYER-NOZZLE.

Specification of Letters Patent.

Patented June 27, 1916.

Application filed May 21, 1915. Serial No. 29,619.

To all whom it may concern:

Be it known that I, ETNA H. DAVIS, a citizen of the United States, residing at Elmira, in the county of Chemung and State of New York, have invented certain new and useful Improvements in Sprayer Nozzles; and I do hereby declare the follow ing to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to water distribution, and more especially to sprayers; and the object of the same is to produce an irr1- gation member for attachment to the delivery end of a hose such as used on the ordinary lawn, which member shall combine a nozzle of suitable structure for use when a solid or broken stream is to be projected and a sprayer for use when the water is to be broken up into a fine spray and the device perhaps left on the lawn for quite a while.

A further object is the provision of means for amplifying or decreasing the volume of the spray, and also the provision of a guard or shield so that the attachment may be laid alongside a path or sidewalk and the spray would be thrown away from the same.

These various objects are carried out in a manner hereinafter described and claimed, and as shown in the drawings wherein:

Figure 1 is a horizontal sectional view of this sprayer nozzle entire, being taken on about the line 11 of Fig. 2; Figs. 2 and 3 are vertical sections on the lines 22 and 33 respectively of Fig. 1; and Fig. 4: is a perspective detail of the shield.

I have shown this device in Fig. l as connected up with the outlet end of an ordinary hose H having the male member m of the coupling which engages the female member F of another coupling on the inlet of the sprayer to be described below; and a nozzle N having the female member f of a coupling which engages the male member M on another nipple on the sprayer, as also hereinafter described. No novelty is claimed for the hose, the couplings, or for the nozzle itself excepting perhaps that it should have a hand valve K, and it is quite possible that the nozzle could be any of those now in common use whereby it is capable of adjustment so that it will throw a solid stream of various sizes or an unbroken stream, as the operator may desire. I may say also that it is quite possible to couple up a number of these sprayers in series or tandem, with lengths of hose between them, the inner length being connected with a source of supply and the male coupling member M of the outermost sprayer being closed, as by a cap or a nozzle N whose valve K is set to close the nozzle which therefore serves at this time as a cap. It will not be necessary to illustrate this tandem arrangement. but a series of sprayers thus coupled up could be led along or around a lawn or garden, and the water turned on so that ampie irrigation would result.

Coming now to the details of construction of the sprayer itself, its body 1 is a box-like structure comprising disk-shaped top and bottom plates preferably between two and three inches in diameter, and an upright circular wall 2 connecting the edges of the top and bottom and producing a cylindrical casmg as well illustrated in the drawings. From the wall 2 at one side a nipple 3 proects tangentially, and on this nipple is swiveled the female coupling F. From the wall at another and nearly opposite point projects a radial outlet nipple 4 whose outer end is shown as formed into a male coupling M. Hence the ordinary course of the water supplied by the hose H is obvious from an inspection of Fig. 1, entering the box-shaped body 1 tangentially and whirling or rotating therein, and leaving the same radially through the outlet nipple 4.

and the nozzle N, whenever the valve K is i opened. Rising from the center of the bottom forabout half the height of the chamber within the body is a post 5 in whose upper end is formed a threaded socket 6; and through the top of the body directly above said socket is a hole 7 (preferably round) surrounded by a boss 8 (preferably square) rising from and probably cast on the top of the box.

A valve or plug is provided, having a thumb piece or handle 11 at its upper end, a shoulder 12 on its shank which is of a size to overlie the boss 8 as seen in Fig. 2, the shank 13 being cylindrical just beneath this shoulder and tapered or reduced a little farther down as seen at 14, and the lower end of the shank being threaded as shown at 15 to engage the threads within the socket 6.

By preference I also provide a guard or shield best seen in Fig. 4:, which comprises an upstanding plate 20, preferably fiat, and having secured to and projecting rigidly at about right angles from its lower edge a lip 21 having a square opening 22 which is of a size and shape to lit closely over the square boss 8 so that the plate will stand upright as best seen. in Fig. 3. This view shows by its arrows how the water flowing out the hole '7 will strike the shield and be deflected by it toward the right in this instance, so that it the sidewalk or path were at the left of the body 1 it would not be sprinkled.

In the use of this device when connected up as seen in Fig. 1, water from the hose H flows through the inlet nipple 3, whirls around within the body, flows out the outlet nipple l, and is delivered by the nozzle N when the valve K is open. If the hose will stand the pressure, this valve can be turned to close the nozzle and no water whatever will then be delivered. It now it should happen that the operator desires to spray his lawn or garden rather than to sprinkle it with the nozzle N, and on the assumption that the latter has no spraying A attachment, he closes the valve K, lays the body 1 on the ground, and opens the plug by turning its handle 11. Immediately the water escapes through the hole 7 and under the shoulder 12. It is quite obvious that the higher the plug is elevated by unscrewing its threads 15 from the socket 6, the higher the shoulder 12 is raised oil the boss 8 until finally the reduced portion 14 of the plug comes into the hole 7 and a considerable volume of water is permitted to escape.

In Fig. 3 the device is illustrated with the plug entirely removed, and with the shield applied for use as above described. In any case, however, when this device is used as a sprayer, the whirling motion imparted to the water in the boX by its tangential inlet, is communicated more or less to the water as it is delivered through the hole 7 and the spray set up, excepting on that side which is baffled by the plate 20 of the shield. Obviously the square opening 252 permits this member being set in any of four positions on the square boss 8, or it could be removed entirely. Although not illustrated, the same result takes place when a plurality of the sprayer attachments are coupled up in series or in tandem. as above suggested, or it is quite possible to have one sprayer inserted in the length of hose and its plug opened more or less, and at a remote point another sprayer with a nozzle N, which latter might be fully or partly in use as desired. In fact, even when the device is laid on the ground and the sprayer at work, it is possible to open the valve K more or less and let the nozzle throw a solid orbroken stream at the same time, perhaps directing it on some particular spot by raising the tip of the nozzle and supporting it on a stone or the like. I reserve the right to use this device in any of the ways suggested or any others which may occur to the operator, and also I do not wish to be confined to the details of construction.

ttention is directed to the fact that the post 5 rising from the center of the boXlike little by little and the water is permitted to flow out hole 7 it strikes beneath said shoulder and is diffused in all directions radially from the plug over the upper end of the boss-that portion of it flowing in one direction striking the plate 20 (if it is used) squarely instead of obliquely as shown by the arrows in Fig. 3 and which would be the case if the plug were entirely removed.

When such plug is adjusted alittle higher,

the tapered or reduced portion 14 of its shank comes into the hole and a greater volume of water is permitted to pass out, but by this time the shoulder 12 will be so high above the boss that it does not diffuse the spray horizontally as just described. In other words, the slight rise of the plug produces a wide and very fiat spray of little volume, raising it a little higher permits the escape of only about the same volume but the spray is directed obliquely upward, raising it still higher increases the volume, and removing the plug increases the volume to the limit of the size of the hole although at this time the swirling or whirling motion already imparted to the water has its great est efi ect on the spray ejected.

WVhat I claim is:

1. In a sprayer nozzle, the combination witha cylindrical boX-like body having a hole through the center of its top and a tangential inlet nipple at one point in its side wall and an outlet nipple at another point, and a plug for adjusting the size of and closing said hole at will; of a coupling on the inlet nipple, a nozzle having means for coupling it to the outlet nipple, and a hand valve within the length of the nozzle. 2.In a sprayer, the combination with a box-like body having a hole through its top surrounded by a raised boss of square outline, means for supplying water to said body, and removable means for adjusting the size of said hole and the direct-ion of the water issuing therefrom at will; of a shield consisting of an upright plate having a horizontal lip projecting rigidly from its lower edge and provided with a square opening adapted to fit said boss in various positions.

3. In a sprayer, the combination with a box-like body having a hole through its top surrounded by a raised boss of angular geometric outline, means for supplying water to said body and imparting a whirling motion to it therein, a removable tapered plug passing through said hole and having a flange above said boss, and means for adjusting the plug vertically to vary the size of the hole and the distance of the flange from the top of the boss; of a shield consisting of an upright plate having a horizontal lip projecting rigidly from its lower edge and provided with a geometric opening adapted to fit said boss in various positions.

4. In a sprayer, a box-like body having a hole in its top surrounded by a boss flat on its upper face, a post rising from the center of the bottom of the body and having in its upper end a threaded socket beneath said hole, an inlet to said body and an outlet therefrom, and means for closing or regulating the size of the latter at will; combined with a plug passing through said hole and threaded into said socket, the plug hav ing a handle at its upper end, a shoulder below the handle with a flat lower face adapted to close upon the upper face of the boss, a cylindrical shank below the shoulder and smaller than said hole, and a tapered portion extending from said shank to the threaded lower end, for the purpose described.

In testimony whereof I affix my signature in presence of two witnesses.
